The Quantico base, started during World War I, has been integral in training, education and forging military doctrine for America's battles.
Early on, amphibious warfare was, the corps said, "conceived and perfected" there. The Marines there came up with the idea "of carrying troops from ship to shore by helicopter."
Now, it's home to the Marine Corps Warfighting Laboratory, which conducts experiments in modern warfare.
"This is perhaps the only command whose mission touches the farthest reaches of the Corps; decisions made here impact Marines aboard ship, fighting in the Global War on Terrorism, on guard duty at embassies across the globe and reserve duty throughout the United States," the Marines said.
Federal agencies, such as the Drug Enforcement Administration and the FBI, share training facilities there.
The base also has a reputation across popular culture as a key national security training location. Jack Ryan, writer Tom Clancy's well-known character in novels and films, for example, took officer training there.
